i love it

Well after reading many reviews, which I strongly urge YOU to do before touching this, I went against my better judgement and thought Id install it and just give it a test run whilst making sure to back up anything I relied on OneTab to handle for me. So I am one of those guys who has anything from 101 tabs to 550 tabs open pretty much all of the time! Yes I know it seems dumb, hogs memory, slows firefox down, drains the system RAM over time...etc, etc, etc but thats what I do because I am a bit scatty and I so often am not finished with reading or going down that particular thought train and really want to continue with it at some point. And so I leave another tab open, planning to revisit. I do admit that my current tab count of 514 is a bit over stupid and I will be culling that number after I submit this review.
So what was my experience? It was not great I can tell you. It resembled what I had read about in manymreviews. In a nutshell: OneTab saved hundreds of tabs as advertised and then when restoring....well, it just didnt! it was as if I had asked it to restore a selection of random links out of the list of over 300 it had made. As if I'd asked it to randomly pick ANY of the links and restore them but only restore less than 50 , one time it reached towards 100 so I was becoming happier hehe. But not happy.
This is DANGEROUS and should come with a warning to expect data loss!!
As I said, I took precautions. I simply created (...or 'saved' I think I should call it, a ne??(w session which is just using the session manager to give me a back up of all of the tabs that were open before I did anything drastic like trust an addon to do what it promised and handle some tab urls and restore them when asked to. Luckily, session manager works great...so does firefox sync, which was my secondary backup I suppose cos I had just sync'd my open tabs and sent them to other firefox open on my other PC and my laptop!
Well dear reader, if there still are any at this point, I want to leave you with some predictable advice so, here goes..l
Please Dont Bother With This!
I dont think it is ready for Prime time. Not quite yet. Too unpredictable for now and too risky for your data to be handled by and trusted with.
If you must have a go then be smart: Do some backup like my method.
DON'T LOSE DATA


*longest review I ever did write

This tab icon is too ugly, I hope it can be replaced.

If I could only have one extention it would be this. Really great. I do wish it had a little better ability to mix and edit saved pages into groups, but for saving memory and cleaning up the 30 tabs i sometimes has it is amazing.

The only thing missing is the night mode, putting this is perfect

Suddenly all my tabs are gone and OneTab shows nothing but a blank page. Have tried reaching out to Devs but they dont respond

Installed this with the hopes of managing the many tabs I have opened.

OneTab took all my tabs, converted it into a list that allowed me to easily review and delete the ones I no longer need.

However, when I tried to restore the clean list of tabs from OneTab back into FireFox, it only restored 5 tabs out of 84.

Buggy and cannot be relied upon if you want to cleanup your tabs. I have since deleted/uninstalled this extension.

When it works its great when things go wrong - things go very wrong.

Firefox crashed lost all links pushed to one tab. Requested assistance multiple time and never got a response.

This is the third time this has happened. I can no longer trust the plugin with saving data.

I hit the OneTab icon accidentally and sent dozens of tabs moved into OneTab. So I hit the Restore All option but only 5 tabs restored.... The rest just vanished.

Quite dangerous to rely on OneTab for your "saved" pages! I lost TWICE in a year MANY of my saved tabs. use it at your own risk!!! Much better to be safe to use Bookmarks instead. Onetab is for light and occasional daily use. You have to ALWAYS worry whenever you do a firefox update and THINK to backup before you proceed... NOT the kind of easygoing addon that devs want you to believe.

It's fairly decent, but losing tabs without a way to get them back is unacceptable for an extension like this.

Super! I really love this add-on. Log my web research in a fast and tidy way. It's very easy to restore all the tabs!

Great addon, simple to use but critically missing dark mode with no third party method to force it to be since "This webpage type" isn't supported by almost anything that tries to edit it's style sheet. Even tried the custom CSS import, but that doesn't seem to work anymore either. With how many reviews I've seen requesting this feature Dark mode seems to almost single-handedly bring it's overall rating down. It's to the point I'm looking for alternatives for eyestrain because of my constant use of this extension. My monitor is only 200 Nit brightness, I can't imagine what higher end monitors might look like.
